Modeling operational expenditures for telecom operators

Abstract

This paper introduces an operational expenditures (OpEx) cost model for telecom operators. In order to give a general overview, all operational expenditures are classified according to a matrix structure. The most important processes to operate an existing network are indicated. The processes for routine operation, reparation, service provisioning and pricing and billing are discussed in detail. Starting from the description of those processes, it is possible to derive formulae to calculate the actual OpEx cost for a certain network scenario. The needed methodology is described in the paper. Finally, we indicate how the used network technology and the offered network services influence the overall OpEx cost.
